Please answer two last questions that are bold.

Be sure you have access to the “Big Data Exercise” excel file. This file will contain data for a list of questions. The “Questions” sheet should show you a list of questions. The “Data” sheet will have the collected data points from the questions. The top row of that sheet will indicate the question number from the other sheet. Please keep in mind that the “Big Data Exercise” file is in no way a representation of Big Data used in the real world.

Feel free to manipulate and organize the data to help you answer the following questions. You will use the data to create graphs or charts to support your statements. You can also sort, filter, group, etc the data as well. The goal of this assignment is to extrapolate useful information, patterns, and find relationships.

Review the “Big Data Exercise” file carefully. Using a minimum of 3 levels data points (questions) what type of services or product would you be able to create that you would sell to these people:

1. What is this product/service? How and why would people use it? Explain.

   1. One possible product to sell to customers would be a dessert and candy store. The store would likely be small and run by 3-6 employees and customers would come to the store as a family or parents would come for their kids to buy delicious, flavorful candies.

2. What are these data points (questions) (3 Minimum) you used to come up with this business?

   1. How old are you?

   2. Do you like spicy food?

   3. Do you currently have a paying job?

   4. How many siblings do you have?

   5. Do you like salty or sweet snacks?

   6. Do you still live with your parents?

   7. How many dependents (children) that lives with you.

1. What calculations and methods from these data points did you use to create the information you need for your business? (Include charts and calculations of average, mean, median, high, or low values) And why these values affect your decision to create this business.
2. Based on the calculated values and data points what demographics would your product/services target? Relate the values from 1c to your explanation.

For this final discussion, I would like you to venture out beyond the information presented in this class and find a news article or magazine article (something "current") that is related to a company software upgrade. Identify what software was updated and why, security concerns, etc. Explain how the story or example works in regards to the things we have focused on in this course. Given your newly acquired knowledge on these topics, what stands out to you from this story? Is there anything you feel could have been done better?  

Write a program to read in a list of domain names from the provided file (domains.dat), and print the reverse domain names in sorted order. For example, the reverse domain of cs.princeton.edu is edu.princeton.cs. This computation is useful for web log analysis. To do so, create a data type Domain, using reverse domain name order. The H file contains the required functions. The compareTo function is provided for you. This will allow you to compare 2 Domain objects.

Also use the StringHelper class provided. The H file of StringHelper outlines all the functions included.

The final list is sorted by as if the list were not reversed.

Below are the given files to complete program.

                                string s = fields[n - i - 1];

                                string t = thatFields[that.getN() - i - 1];

                                int c = s.compare(t);

                                if(c!= 0)

                                                return c;

                }

                return 0; //strings are equal

Here are summary statistics for randomly selected weights of newborn​ girls: n=164​, x=28.7 ​hg, s=6.3 hg. Construct a confidence interval estimate of the mean. Use a 95​% confidence level. Are these results very different from the confidence interval 28.0< μ <29.8 hg with only 19 sample​ values, x=28.9 ​hg, and s=1.8 ​hg?

What is the confidence interval for the population mean?

Calendar Program

Write a program to design an appointment calendar. An appointment includes a description, date, starting time, and ending time. Supply a user interface to add appointments, remove canceled appointments, and print out a list of appointments for a particular day.   Appointments should not be duplicated for a given time and date.

Include a class AppointmentMenu to print the menu to the screen and accept user input. AppointmentMenu creates an AppointmentCalendar and then calls the appropriate methods to add, cancel, show, or quit.

Include a class AppointmentCalendar that is not coupled with the Scanner or PrintStream classes. (In other words, all println statements should be in AppointmentMenu.) AppointmentCalendar will include an arrayList of Appointments, a method to add Appointments, a method to cancel Appointments, and return the Appointments for a selected day.

Include a class Appointments which holds the input of description, date, and time. It should have a method to format the output for printing by the AppointmentMenu, a method to check to see if two appointments are equal so an appointment is not duplicated for a given date and time, and a method to check for a certain date when show and cancel are called.   

Be sure to include any other methods including any accessor methods that you need to complete this program using the design process described in Chapter 12.

Your main class should be called AppointmentSystem. Use the code below:

/**
 A system to manage appointments.
*/
public class AppointmentSystem { 
   public static void main(String[] args) {
      AppointmentMenu menu = new AppointmentMenu();
      menu.run();
   }
}

Here is a sample program run. (bold items are sample user inputs).

Business ethic class. chapter 8.

Explain how to estimate the cost of capital. In particular, explain how to estimate the equity cost of capital, list two different methods to estimate the debt cost of capital, and how to calculate the weighted average cost of capital for a given debt-equity ratio.

Question 1: You manage the cost of a meal for a shelter. You have three menu items to serve: chicken, carrot and potato. You must meet minimum nutritional requirements for the meal while managing cost:

                                    Chicken        Carrot       Potato

Cost $/kg                      $8.25          $2.85          $3.75

Calories cal/kg              1430            410           1990

Fiber g/kg                         5.0             37.0           28.0

Protein g/kg                    170                  9              29

You are to decide how many kg of chicken, carrots and potato to serve to minimize the cost to the shelter.

You are constrained by each meal must provide a minimum of 650 calories, 15 grams of fiber and 35 grams of protein.

Each meal must include at least 0.05 kg of each item.

What is the cost? Use Solver to to optimize this related set of equations.

This is a linear programming/optimization problem. Follow the pattern of solution shown in the lesson to solve this problem. PLEASE USE EXCEL!

1- The low-cost provider has an advantage where product offerings in a market are similar and more-or-less interchangeable. Why is this? In a differentiation strategy, would one expect higher margins or lower margins, and what are some common bases of differentiation? What does it mean to say that a company strategy is “stuck in the middle”?

2- When a company looks at its portfolio of businesses in a BCG analysis, it probably sees no value in having “dogs” in the portfolio, but a balance in the other three sectors would be valuable. Why would some constituent businesses in each of the other three quadrants (star, cash cow, question mark) be desirable?

3- For a football season, how might a college enhance the experience for a number of groups of fans by offering “multiple strategies”?

1. What kinds of behaviours might alert an early childhood educator to the possibility that a child could be developing more slowly than typical? What are some practical things to remember when working with the child?

6. a. Using a machine element , describe fatigue in engineering materials . Why is fatigue loading more dangerous than normal loading. As a design engineer, how can you prevent failure by fatigue.
d. A building collapsed in a city last month. List all possible reasons that could have caused the failure and how these could have been prevented.

c. What is the effect of extreme temperatures (too low or too high) on the property of material ( yield strength, ductility, toughness, brittleness , fatique strength)

HOUSE OF REPRESENTATIVES

SENATE

COMBINED TABLE – CONGRESS COMBINING HOUSE OF REPRESENTATIVES AND SENATE

Congress if made up of the House of Representatives and the Senate. Members of the House of Representatives serve two year terms and represent a district in a state. The number of representatives each state has is determined by population. States with larger populations have ore representatives than stats with smaller populations. The total number of representatives is set by law at 435 members. Members of the Senate serve sex-year terms and represent a state. Each state has 2 senators, for a total of 100. The tables show the makeup of the 111^th Congress by gender and political party. There are two vacant seats in the House of Representatives.

Please answer the questions below and SHOW YOUR WORK where applicable.. all answers should be proportions rounded to the nearest thousandths (3 decimals) for instance this is what is required to be shown if I ask and answer the following question:

Find the probability that a Senate is a Male or a Democrat:

83/100   +    57/100     –     44/100     =      96/100   =    .960

1. Find the probability that a randomly selected House of Representative is a female.

2. Find the probability that a randomly selected Senator is a female.

3. A House of Representative member is selected at random. Find the probability of each event:
   1. The representative is a male

2. The representative is a Republican

3. The representative is a male GIVEN that the representative is a Republican

4. The representative is female and a Democrat

4. A Senator is selected at random. Find the probability of each event
   1. The senator is a male

2. The senator is not a Democrat

3. The senator is female or a Republican

4. The senator is a male or a Democrat

5. Using the same row and column headings, create a combined table for the Congress (template created for you above)

6. A member of Congress is selected at random. Use the combined table to find the probability of each event.

1. The member is Independent

2. The member is female and a Republican

3. The member is male or a Democrat

It is absolutely critical that international businesses understand the influence of exchange rates on the profitability of trade and investment deals. Foreign exchange risk can be divided into three main categories: transaction exposure, translation exposure, and economic exposure. Talk about some ways that risk in these three areas can be minimized.

Assume that the 129 patients in the Patients dataset represent the entire population of interest. If you were interested in age of the patients and took a sample of 25 patients from this population, what is the standard error of the mean?   What if you took a sample 64 patients from this population, what is the standard error of the mean? What happens to the standard error of the mean as the sample size increases?  If you select a sample of 64 patients, what is the probability that the sample mean is below 75? How to calculate in excel.
